I have an ovulation scope and i have been using it and the pattern has been regular ferning, but today the pattern was still ferning but it was really large they just looked bigger than usual. The ferning pattern has been coming up since the 17th and it is already the 22nd that seems long to me.Has anyone else ever used the ovulation scope and experienced this , my last period was on may 17th and then on june 10th. I recently got my iud removed in april and really not sure how long my cycle is. Basically i just want to know if the ferning is supposed to be small all the time and why have they gotten so large all of a sudden.
